Title: Hetero junction bipolar transistor
Inventor: NOZAWA KATSUYA
IPC: H01L29/737
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a hetero junction bipolar transistor(HBT) using SiGeC. SOLUTION: Sequentially grown on a p type Si substrate 61 are a high- concentration, n type region Si layer 62, an n type Si layer 63 thereon to be later used as a collector region, a p type Si layer 64 thereon to be later used as a base region, and an n type SiGeC mixed crystal layer 65 thereon to be later used as an emitter region. These layer are epitaxially grown to avoid generation of dislocation of respective junction interfaces. With such an structure, the substrate, the collector region, the base region and the emitter region are set to have an identical lattice constant of Si, so that lattice misalignment caused by the hetero junction will not take place and thus lattice defects caused by distortion resulting from the lattice misalignment will not occur.  Due to the lattice alignment, a critical film thickness is not present and thus a film can be crystal-grown to a desired thickness. In this way, when the emitter region is made of the SIGeC mixed crystal, a problem of lattice misalignment, which would be inevitable in a conventional HBT based on SiGe mixed crystal, can be solved.

Title: Waveform shaping circuit
Inventor: SATOU KATSUMI
IPC: H03K17/66
Filed: 1981-06-15
Abstract: PURPOSE:To form two pulse waveforms which are not on-state at the same time, by using an input and output coupling element having a delay transfer characteristic such as a photocoupler. CONSTITUTION:When a rectangular pulse is applied to a transistor TR3, a collector potential of a TR2 is lowered and an output Q1 goes to L level. A photo  TR1 turns on with the illumination of an LEDL1 and an output Q goes to H  level with a delay. Thus, since a voltage across an LEDL2 goes to H level,  the LEDL2 is distinguished. Then the TR2 turns off. When an input pulse goes  to L level, since the TR3 turns off, the LEDL1 is distinguished, the TR1 turns  off and an output Q2 goes to L level with a delay. Since the LEDL2 again turns  on, the TR2 turns on and the output Q1 goes to H level with a delay. Thus, two pulse waveforms which can not be turned on at the same time can be  formed and an output similar to a sinusoidal waveform can be obtained by using  the pulses for the driving circuit of an inverter.
